I'm using Gordon Messmer's excellent pythonfilter package[*]. What I'd like to do is to cause special code to be invoked during its startup for the purpose of making common data available to all the filters.

For example, there is a subset of domains that I host for which I want to do special spam filtering. I'd like to read this list at startup and store the set of domains in some sort of data structure that would be available to all of the filter modules.

Is this possible without changing the pythonfilter code, or will I have to hack in this capability?

Thanks in advance.
